  • Gas barrier coating having improved bond strength
    Patent number: 8268108
    Abstract: In order to maintain adequate bond strength of a composite in which a gas barrier coating comprising a clay dispersion and a polymer solution or dispersion of a PVA and/or EVA is positioned between two flexible plastics films using an adhesive, it is necessary that the clay dispersion and the polymer solution or dispersion should be kept separate until shortly before they are to be applied.
